If you configure/build OMPI on the remote node using the same configure options
you used on host1, does the problem go away?

The problem is likely that your path variables aren't being set properly on the
remote machine when mpirun launches the remote daemon. You might check to see
that your default shell rc file is also setting those values correctly.
Alternatively, modify your mpirun cmd line a bit by adding
mpirun

Hi,
hast du das Problem nur mit OpenMPI oder auch mit anderen MPI Bibliotheken

Ansonsten kannst du auch mal probieren, ob du das All-to-all mit Collectives
hin bekommst, z.B. Scatter oder Gatter.
Viele Grüße
